Given numbers are 286, 576, 257, 865

The list of prime factors of all numbers are

Prime factors of 286 are 2 x 11 x 13

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 257 are 257

Prime factors of 865 are 5 x 173

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 286, 576, 257, 865

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(286, 576) = 82368

GCD(286, 576) = ( 286 x 576 ) / 82368

= 286 / 576

= 286

Step2:

LCM(2, 257) = 514

GCD(2, 257) = ( 2 x 257 ) / 514

= 2 / 257

= 2

Step3:

LCM(1, 865) = 865

GCD(1, 865) = ( 1 x 865 ) / 865

= 1 / 865

= 1

So, Greatest Common Divisor of 286, 576, 257, 865 is 1
